In general, the present disclosure relates to an attachment for a vacuum cleaner. The attachment is moveable between a first position and a second position to allow a user the ability to clean a variety of areas.

As shown in FIG. 1, a cleaning tool 5 (e.g., a handheld vacuum cleaner) is coupled to an accessory tool 10 and used to clean a surface. The cleaning tool 5 includes a source of suction (not shown) that may draw air and debris through the accessory tool 10 and into a container (e.g., a dirt cup—not shown) within the cleaning tool 5. The cleaning tool 5 includes a handle 7 that a user may grip in order to direct the suction.

As shown in FIG. 2, the accessory tool 10 includes a conduit or cleaning wand 14. The wand 14 includes a first end 16 that is configured to attach to the vacuum cleaner 5 and a second end 17 that extends away from the first end. In the illustrated embodiment, the wand 14 is a rigid member, although in other embodiments, the wand 14 may be flexible or bendable.

An attachment or knuckle 18 is coupled to the wand 14. In the illustrated embodiment, the knuckle 18 includes a first part 22 and a second part 26. Each part 22, 26 includes a passageway 30 (FIGS. 3A and 3B) that extends through a body of each part 22, 26. The passageways 30 are substantially the same size and shape as the wand 14 (e.g., circular). In the illustrated embodiment, a flexible tube or hose 32 extends from the first part 22 to the second part 26 to provide fluid communication between the passageways 30 of the first and second parts 22, 26.

As shown in FIGS. 3A and 3B, the first part 22 is pivotable relative to the second part 26 about a first axis of rotation 33. In a first position (FIG. 3A), the passageway 30 of each part 22, 26 is aligned along a common axis 34. Additionally, the flexible hose 32 is also aligned along the axis 34. In the second position (FIG. 3B), an axis 34a that extends through the passageway 30 of the first part 22 is oblique with respect to an axis 34b that extends through the passageway 30 of the second part 26. In the second position, the flexible hose 32 bends as the parts 22, 26 move with respect to one another. The first part 22 includes a channel 35 that receives a projection 36 (FIG. 5) of the second part 26 in the second position. In the illustrated embodiment, the channel 35 includes a semi-circular shape. The engagement of the channel 35 and the projection 36 limit further rotational movement of the first part 22 with respect to the second part 26, and help maintain the knuckle 18 in the second position.

As shown in FIGS. 2 and 4, a nozzle 38 is coupled to the knuckle 18. In the illustrated embodiment, the nozzle 38 includes a hub 42, a first portion 46a, and a second portion 46b. The hub 42 includes a passageway 50 (FIG. 5) that slides onto the second part 26 and is coupled to the knuckle 18 (e.g., via a friction fit, a detent, a latch, etc.).

The first portion 46a and the second portion 46b are movable coupled to the hub 42. In the illustrated embodiment, hub 42 includes pins 54, and the first portion 46a and the second portion 46b are pivotable about the pins 54 about a second axis of rotation 47 that extends through a plane that is generally orthogonal with respect to the first axis of rotation 33. In other words, the first and second parts 22, 26 pivot in a first direction and the first and second portions 46a, 46b pivot in a second direction. Each portion 46a, 46b includes a channel 58 defined by two side surfaces 62 and an end surface 63. In the illustrated embodiment, a portion of each side surface 62 is arcuate or curved and includes teeth 66. In some embodiments, the teeth 66 extend around an arc of 90°, while in other embodiments, the teeth 66 may extend greater than or less than 90°.

FIG. 2 illustrates a first cleaning position for the nozzle 38. In the first cleaning position, the side surfaces 62 of the first portion 46a and second portion 46b are adjacent to or contacting one another. The channels 58 are aligned in a facing relationship to define a common channel that extends along the axis 34 (e.g., openings to the channels 58 are adjacent one another). The first cleaning position defines a narrow profile and allows the accessory tool 10 to clean tight areas or crevices. In the first cleaning position, only the end surfaces 63 of the first and second portions 46a, 46b are exposed to a surface to be cleaned. A cleaning area of the first cleaning position is defined as the opening between the adjacent end surfaces 63 (e.g., the area of the channels 58).

As shown in FIG. 5, the first and second portions 46a, 46b are pivotable to a second cleaning position. In the illustrated embodiment, each portion 46a, 46b is pivotable approximately 90° in opposite directions (e.g., the first portion 46a pivots approximately 90° clockwise and the second portion 46b pivots 90° counterclockwise). As the portions 46a, 46b pivot, the teeth 66 on the first portion 46a engage the teeth 66 on the second portion 46b. Teeth 66 allow a user grasp one the portions 46a, 46b, and cause both of the portions 46a, 46b to pivot as well. In other words, a user only needs to grasp one portion 46a, 46b in order to rotate both portions 46a, 46b. In the second cleaning position, each channel 58 extends along an axis 70 substantially perpendicular to the axis 34b. The side surfaces 62 and the end surface 63 of each portion 46a, 46b are exposed to the surface to be cleaned. A cleaning area of the second cleaning position is defined as the area between the side surface 62 and between each end surface 63. The cleaning area of the second cleaning position is greater than the cleaning area of the first cleaning position.

A detent 74 on the hub 42 engages an aperture 78 on each portion 46a, 46b to lock the first and second portions 46a, 46b in the second cleaning position. The second cleaning position provides a wide cleaning area along the length of axis 70 and has a larger surface area than the first cleaning position. The second cleaning position can be used to clean floors (e.g., hardwood floors).

In both the first cleaning position (FIG. 2) and the second cleaning position (FIG. 5), the wand 14 extends only into the passageway 30 of the first part 22, allowing the knuckle to pivot between the first position (FIG. 3A) and the second position (FIG. 3B). The user may pivot the knuckle 18 in order to allow for more ergonomic usage. The flexible hose 32 provides fluid communication between the passageways 30 of the first and second portions 46a, 46b and the passageway 50 of the hub 42. This allows the vacuum cleaner (not shown) to suction air and debris within the channels 58 up through the wand 14.

As shown in FIG. 6, the user can move the nozzle 38 to a storage position when the nozzle 38 is no longer required (e.g., because the user wants to use an alternate accessory). In the illustrated embodiment, the knuckle 18 and the nozzle 38 remain coupled to the wand 14 while moving between the operating position (FIGS. 2 and 5) and the storage position. With the knuckle 18 in the first position (FIG. 3A), a user may slide the wand 14 through the passageways 30, 50 and the flexible hose 32. The portions 46a, 46b move toward or into the second cleaning position, allowing the wand 14 to slide past the channels 58. The nozzle 38 and knuckle 18 are stored on wand 14 and away from an end 82 of the wand 14, thereby allowing the wand 14 to be used by alone or with other attachments. The user may slide the knuckle 18 and nozzle 38 back toward the end 82 of the wand 14 to continue to use the nozzle 38.

The embodiment(s) described above and illustrated in the figures are presented by way of example only and are not intended as a limitation upon the concepts and principles of the present disclosure. As such, it will be appreciated that variations and modifications to the elements and their configuration and/or arrangement exist within the spirit and scope of one or more independent aspects as described.
